Trevor is the most dedicated of the cockatiels to maintaining the nestbox. He’s been chewing away at the opening.
Trevor likes to chew the nestbox as he pushes it. The nextbox eventually falls off the cage and he’s surprised. So you can see in the picture above that there’s a white string to the left of the green mineral block. I used yarn to secure the nestbox to the cage.
Trevor is in his cage right now because along with being territorial about the nestbox, he’s taken to charging Stonewall. Stonewall is no longer the dominant bird. Trevor is the most aggressive bird, but since both he and Stonewall defer to Conner, I think Conner is the leader. Lucky for me, Trevor doesn’t actually mind being put into the cage as long as Conner is nearby. Conner loves Trevor too, so he doesn’t stray far.
The picture below is so funny. I was trying to get a good shot of Trevor and instead I got a perfect picture of Stonewall and Conner peeking from behind the nestbox.
